What indication on the magnetic compass would you expect while rolling into a standard rate turn to the right from an easterly heading in the Northern Hemisphere?

When rolling into a standard rate turn to the right from an easterly heading, one can expect that if the roll into the turn is performed smoothly, the magnetic compass will indicate the approximate correct magnetic heading throughout the maneuver. This occurs because, during a gradual turn, the compass is able to adjust and reflect the aircraft's true heading with relative accuracy.

In the Northern Hemisphere, the magnetic compass experiences a phenomenon known as "turning error," but when the turn is executed smoothly, the compass card has time to stabilize, thus displaying the correct heading that corresponds to the aircraft's actual path.

Understanding this helps recognize that it is the gradual nature of the turn, rather than abrupt maneuvers or rapid changes in bank angle, that allows the compass to remain accurate and helpful for navigation. The compass's ability to maintain a close approximation of the heading benefits pilots in assessing the direction and maintaining situational awareness during instrument flight.
